Gamma Knife stereotactic radiosurgery is a procedure in which high-dose ionizing radiation beams are precisely aimed at lesions in the brain, causing them to shrink or stop growing.

If you are scheduled for Gamma Knife treatment, one of our trained Gamma Knife nurses will call you with specific instructions prior to the day of your procedure. Here are some basics on what will happen leading up to Gamma Knife radiosurgery and what you can expect at the Rocky Mountain Gamma Knife Center.


Leading Up to Gamma Knife Treatment for Brain Tumor

One of the major benefits of Gamma Knife radiosurgery is minimal downtime. Gamma Knife patients typically arrive at our Center in the early morning of treatment and stay for about five to eight hours. Most Gamma Knife patients can return to work and normal activities within one to two days. You’ll want to arrange for time off work, childcare, pet-sitting, etc., for the day of treatment and possibly the next day. Read more about what you can expect after treatment.

Gamma Knife radiosurgery does not require general anesthesia. You will receive light sedation to keep you relaxed throughout the procedure along with a topical anesthetic to the head where the headframe will be placed. You’ll need to have a friend or family member drive you home afterward. He or she can stay with you during much of the day to keep you company, if you would like.


The Morning of Gamma Knife Treatment

Take regular medication as prescribed unless advised otherwise. Do not eat anything. Dress in comfortable, loose-fitting clothing, and do not apply makeup or heavy hair products. Leave all jewelry, watches, and other valuables at home. You may keep dentures in.

Gamma Knife radiosurgery requires precise planning that is done on the day of the procedure to ensure the most accurate and beneficial treatment. There will be downtime between the imaging and the procedure while your physician works with another specialist to develop your treatment plan. You may wish to bring a book, magazine, or tablet to pass the time.
